A correct XY calibration will ensure that the two colors or materials align well.
The print cores that are supplied with the UltiMaker S7 are already calibrated. For any new combination of print
cores,anXYosetcalibrationmustbeperformed.Theprinterwillthenstorethiscalibrationvalueinternally.
To perform the calibration, you will need the XY calibration sheet as a reference, which is included in the accessory
box. Ensure two print cores and materials are installed before starting the calibration.
